Frequently Asked Questions

Expert Insights into Solar DC Surge Protection

What is a DC Surge Protective Device (SPD)? +
A DC SPD is designed to protect solar PV systems from transient overvoltages caused by lightning strikes or grid switching, diverting the surge current to the ground.
Where should the SPD be installed in a solar system? +
SPDs should be installed at both the DC input of the inverter and the DC output of the solar array (typically in the combiner box) for comprehensive protection.
How do I know if the SPD module needs replacement? +
Our SPDs feature a visual status window. A green indicator means the device is functional, while a red indicator signifies that the module has reached its end-of-life and must be replaced.
Do you provide customized voltage ratings? +
Yes. As a manufacturer, we can produce SPDs with specific Uc (Maximum Continuous Operating Voltage) ratings ranging from 500V to 1500V DC to suit your unique project needs.
